Failed to load project for workspace

[amirhosseindavoody]

Summary

I am using ty extension on VScode with the following project settings

        "python.defaultInterpreterPath": "${workspaceFolder}/.pixi/envs/py/bin/python",
        "python.languageServer": "None",
        "ty.importStrategy": "useBundled",
        "ty.interpreter": [
            "${workspaceFolder}/.pixi/envs/py/bin/python",
        ],
        "ty.disableLanguageServices": false,
        "ty.inlayHints.variableTypes": false,

The python and other depenencies is installed using pixi in the local directory.

The extension is not able to resolve the python environment.

As a note, the same settings used to work in a different vscode workspace, but it is giving me error here. I did a couple of reload windows and one of them seemed to work but it appeared again after some time.

My development environment is that I am connecting from windows to my WSL machine. I have latest VScode, Pixi and TY extension.

Here is the ty logs:

Hi.

I'm sorry you're running into this and thanks for sharing all the logs. They're very helfpul.

Can you double check what interpreter you've selected in VS Code and if it is correct. To do so, open the command pallete (Cmd+Shift+P), "Python: Select interpreter", select the environment for this workspace.

(This might be unrelated but the only purpose for the ty.interpreter is to provide the Python interpreter to use for finding the ty executable and it's not the same as ty.environment.python)

Thanks for the tip. Adding ty.toml file with the following content fixed the issue.

[environment]
python = "./.pixi/envs/py/bin/python"

Also, before adding the ty.toml file, I tried selecting the correct python Interpreter, but it didn't help.
